Allen-Bradley 1756-RIO ControlLogix Remote I/O Communication Module

Overview
The Allen‑Bradley 1756-RIO is a Remote I/O communication module designed for use in ControlLogix programmable 

automation systems. It provides a seamless communication interface between a ControlLogix controller and a Remote 

I/O network, enabling legacy or distributed I/O devices to be integrated without requiring extensive changes to existing 

field wiring. The module can operate as either a scanner or adapter, facilitating data exchange across Remote I/O racks 

and handling digital, analog, specialty, and block‑transfer data transparently without the need for explicit message 

instructions.
